Morse Code Ninja Sticker
from Kurt Zoglmann, ADØWE, January 2021
If you would like a Morse Code Ninja Sticker, please reply directly to me with your callsign (or your address, if it is different than the one listed on QRZ). I would be happy to send you one. The stickers are four by two inches. They are UV resistant and waterproof, so you can put them on your car window, or even just a laptop/computer.
I have been sending out many stickers to celebrate my Morse Code Ninja website – https://morsecode.ninja, which is a great resource to learn more about Morse code. I have a Morse Code course, 1,000s of hours of practice to help you improve proficiency up to 50 wpm (and select content up to 100 wpm), and a comprehensive list of related resources. (If you are accessing the website on a phone, click the hamburger-looking icon in the upper-right corner to access the other pages.)
I normally ask for an SASE or a $5 donation, but I'm happy to give back to our local amateur radio club. :) I wish you all the best on your Morse code journey!

Morse Code Speed vs. Proficiency
from Kurt Zoglmann, ADØWE, December 2020
Kurt says, "I wrote this story for my Morse Code Ninja website's Advice page — https://morsecode.ninja/advice/index.html. I thought at least a few in the club would find it of interest, perhaps even inspiring. Have you ever wondered what is involved in copying Morse code at high speed?
The unconscious mind's lightning-fast ability to process information is the key to copying code faster. As a general principle, as the Morse code speed increases, a larger amount of the processing and interpretation must be done by the unconscious mind. And this is directly related to the four levels of Morse code proficiency.
Levels of Morse code proficiency:
1. Conscious decoding of Dits and Dahs
2. Instant Character Recognition
3. Instant Word Recognition
4. Focus on the Meaning"
webmaster's note: Kurt's extensive comments on CW proficiency went out to MAARS members. He has a page on learning to copy two and three words at a time. Finally, Kurt has a YouTube video, Morse Code Speed vs. Proficiency.
Lunch SSB Roundtable
from Bill Dickinson, WSØI, September 2020
We have several folks who get on 3.805 MHz almost every day, from around 11:30 to 12:30 or so. It started when COVID-19 hit in March, and I was working from home. It has continued since then, even after going back to work, as I also run 80 meter mobile in my truck. We talk about anything and everything: radios, weather, news, etc. We have also been getting some of the older hybrid gear on the back on the air. So, if you happen to find yourself wondering what to do around this time every day, jump on and jump in for a bit. Everyone is welcome.

Noise and Interference Mitigation Techniques
by Bill Dickinson, WSØI, May 2020
Bill says, "I thought I would provide a bit of online Elmering. I believe all of us are using fairly recently designed equipment, and I thought I would share a few tips and tricks for HF and VHF/UHF phone operations."
- [RX] Use your IF shift and IF Width Filters to move an interfering signal out of your receiver's passband, and utilize your Low Cut/High Cut filters to narrow your IF passband.
- [RX] If your equipment had DSP Noise Reduction utilize it, and if it is adjustable, play with the levels controls too much and you will start hearing DSP artifacts and distortion, so you have to vary it with conditions.
- [RX] The Noise Blanker can be a blessing and also your worst enemy. If it is a fixed type, you are stuck with on or off. If it is the adjustable type, less is more, and again setting it too high will cause AGC pumping action, distortion, and well as generate spurs throughout your receiver.
- [RX] The AGC Control another blessing and your worst enemy. Many are fixed with your options being Fast, Medium, Slow, time constants or Auto. Swap back and forth and see how your receiver acts between Slow and Medium. Do not rely on Auto.
- [RX] RF Gain: They made this adjustable for a reason, and everybody runs that baby cranked all the way to the right, that's your starting point, but did you know if you back that off, and increase your AF gain level, you would be amazed at the weak signals that pop up out of the noise that were being blocked by the AGC circuit action when it was running full bore.
- [RX] If you have a newer DSP based transceiver, adjust your receiver bandwidth filters, 1.8K, 2.1K, 2.4K 2.6K, 2.8K, 3K and if it allows for filter shaping, choose hard or soft shoulders as conditions warrant. A 1.8k will not be pleasant to listen to for very long, but it can help. Try different widths. Some allow you to create your own. Most transceivers default to 2.4, 2.6 or 2.8K.
- [RX] For the older rigs that utilize Crystal filters, if your rig does not have them installed, as many do not as these were options, look on the swap pages. Some can be found for reasonable prices, and 3rd party aftermarket filters which btw are actually better than the manufacturers' filters, are still available for many of the older popular rigs.
- [TX] The Speech processor, and or Compressor, utilize these as conditions warrant. Again less is more, but what will do is increase your average talk power, as well as boost your transmitted audio.
- [TX] If your newer DSP rig supports adjustable Transmit bandwidths, adjust these as needed. Many default to 2.4K or 2.6K, with low cutoff usually defaulting to either 200 or 300 Hz, and the High cutoff at 2600 to 2900 Hz.
John T. Frye's Carl and Jerry (from Popular Electronics)
from Myron Calhoun, WØPBV, May 2020
You don't have to be old to enjoy John T. Frye's Carl and Jerry stories, published in Popular Electronics from 1954 thru 1964 (119 stories altogether!), but it might help! -) Visit www.copperwood.com/carlandjerry.htm for "the rest of the story" (kudos to Paul Harvey), and for 10 stories you can download as PDF files.
I am attaching the first one, just to whet the appetite of all you young whippersnappers who haven't heard of Carl and Jerry before.
Harvard University Study on Morse Code in 1943
from Kurt Zoglmann, ADØWE, May 2020
I had the day off, and spent the afternoon restoring a fascinating research paper on Morse Code from Harvard University, released in the Journal of Psychology in July 1943! (PDF attached)
The outbreak of World Word II created a massive demand for the United States to train men in the use of the International Morse Code, perhaps as many as 10,000 men per month! The problem was that 30 to 60% of men entering radiotelegraphy schools failed to become proficient operators. The author, Donald Taylor, carried out experiments to determine aptitude and ways to shorten the length of time necessary to train men to become proficient with Morse code. The results are fascinating! And some of it goes against commonly held beliefs in the amateur radio community, even today!
I hope some of you will enjoy it!
All About Spectrum Scopes
from Kevin Loughin, KB9RLW, April 2020
KAØJPM here. I happened across an outstanding 27-minute YouTube video... an explanation of spectrum scopes, waterfall displays, etc., such as you'd see on an ICOM IC-7300. KSUARC has this radio, and until watching this, I had very little understanding. I don't know if I've ever seen a better instruction video. (link)
Remotely Administered Amateur Radio Exams
The ARRL Letter, April 2020
Facing a growing demand for amateur radio exam sessions in a time of stay-at-home orders, sponsors of some Volunteer Examiner teams are developing systems to remotely proctor test sessions. "Many of our VEs and VE Teams have been working on remotely proctored exam session ideas, employing both video and in-person components -- following social distancing protocols," ARRL-VEC Manager Maria Somma, AB1FM, said. Some teams are using a combination of Zoom and fill-and-sign Adobe PDFs. (link)

Morse Code Ninja
from Kurt Zoglmann, ADØWE, April 2020
"My interview on the DitDit.fm podcast was released recently: Episode #29 – Morse Code Ninja. Feel free to check it out! Bruce (N9WKE) was a lot of fun to talk to! It was a joy talking to him about my love and passion for Morse Code. We also spoke about my Morse Code Ninja web site, and many other tips for learning Morse code."
Jan. 31, 2020: From Ryan Benteman, ADØTZ: Repeater Upgrade Announcement
As most of you know already, the KSØMAN 147.255 repeater was upgraded this afternoon. The two old repeaters were removed, and 125w Motorola Quantars were placed in their spot, along with a new duplexer set. This is still a full analog-only radio on the same frequency, with a tone of 88.5.
First off, many thanks to everyone who's helped with getting this repeater upgraded, both monetarily and physically. It's been a long process since October, when we started looking into the prospect of upgrading or repairing our Mastr II machine, and I'm pleased that the club now has a matching pair of very high quality repeaters that should last well into the future for us.
It still has battery backup, utilizing 200ah of UPS-grade backup batteries. The transmit power is 100w when it is under normal AC power, and 50w when under battery backup power.
The controller is different than what we had before. The repeater gives a CW ID every 10 minutes, and after transmission is a Nasa Quindar tone, with the same squelch tail length that the prior machine had. There are no voice announcements, no intros, just a CW ID and a beep after transmissions.
So far, initial reports are good, but I look forward to hearing any signal reports or problems you have with it. Our transmit power is the same as before, so I don't expect a coverage change, but it could have slightly better reception on the fringes.
